The 57,000m scheme for client Cityzen is on the site of a former Soviet military headquarters at the corner of Mikheil Tamarashvili and University streets in the Saburtalo district.The mainly residential skyscaper will sit at the gateway to a wider housing-led neighbourhood, which is already under construction, and is being billed as a vertical extension of Tbilisis new 36ha Central Park. The neighbouring four block will provide 886 homes with a further 405 apartments in the ZHA-designed tower.The practice said a series of cascading landscaped terraces will extend from the tower towards the park, providing south-facing outdoor spaces for cafs, restaurants and other community activities on the lower floors.AdvertisementThese terraces will act as social areas for the lower-level office floors and as balconies for the flats above.The London-based ZHA team is collaborating with local firm Artstudio Project on the designs. It is understood the Georgian studio had worked on previous iterations of the landmark tower.ZHA recently posted a global fee income of 77.3 million for the 12 months to 30 April 2024, up by 7.8 million from the 69.4 million made in 2023. All but 1.7 million of the practices turnover came from projects outside the UK.The skyscaper is expected to complete in 2028.Architects viewInformed by the rolling hills intersected with river valleys that wind through the undulating cityscape of Tbilisi, Cityzen Towers design by Zaha Hadid Architects echoes its context at the intersection of the citys urbanism and its natural environments.The towers composition is defined by the gradual unification of the large communal areas facing the park on its lower floors merging into the smaller, diamond-shaped footprint of the residences above. This design ensures every apartment has excellent natural lighting conditions and exceptional views. These differing footplate requirements between the lower and higher floors gradually amalgamate, defining an incremental twist in the towers overall composition.Detailed local wind and solar analysis has also informed elements of the 42-storey towers design to ensure optimal comfort for residents and visitors to Cityzens public plazas, outdoor terraces and recreational areas.Situated within Tbilisis humid temperate climate, the Cityzen Tower is designed to optimise natural ventilation. Its extended balconies and external louvres will minimise direct sunlight in summer and enhance solar radiation in winter to further reduce energy demand.The towers concrete structure continues the tradition and expertise in concrete construction of Tbilisis local suppliers and workforce. Designed to achieve LEED Gold certification, the towers procurement will target the use of locally recycled materials when available. The Cityzen development will also implement rainwater collection and reuse via its on-site reservoir. All planting throughout the complex will use native vegetation that does not require supplemental irrigation.
